How to convert Satoshi core to BTC?

Could you please explain to me how to convert Satoshi core to BTC? I've been hearing a lot about cryptocurrencies lately and I'm trying to wrap my head around the different units and conversions. I understand that Satoshi is a subunit of Bitcoin, but I'm not quite sure how to go about making the conversion. Could you provide a step-by-step guide or perhaps a formula that I can use to make the calculation? It would be greatly appreciated if you could help me understand this better. Thank you in advance for your assistance.
